Solid lithium batteries have been regarded as a kind of promising power battery for electric vehicles in view of their high energy density, long cycling life, and excellent safety. As the key component of solid lithium batteries, the solid electrolytes include oxide electrolyte, sulfide electrolyte, polymer electrolyte, and composite electrolyte. Except for the traditional materials for aqueous lithium ion batteries, high-voltage cathode materials are also suitable for solid lithium batteries. As for anode materials,silicon-based material and metallic lithium are favorable options rendering high capacity to the solid batteries. The industrialization status and future perspective of solid lithium batteries were also presented in this paper.
